Efficacy of Wireless Pacemaker Combined with PCI for the Treatment of Acute Myocardial Infarction with Arrhythmia and Its Impacts on Electrocardiogram and Adverse Cardiovascular Events
Objective:To observe the efficacy of wireless pacemaker combined with percutaneous coronary intervention(PCI)for the treatment of acute myocardial infarction(AMI)with arrhythmia and its impacts on electrocardiogram and adverse cardiovascular events.Methods:A total of 80 patients with AMI complicated with arrhythmia who were treated with wireless pacemaker combined with PCI were selected.The implantation status of wireless pacemakers,the effectiveness of PCI surgery,cardiac function,myocardial perfusion grading,pacemaker electrical parameters,electrocardiogram,reperfusion injury,and adverse cardiovascular events were analyzed.Results:All patients met the criteria of coronary artery recanalization with interventional therapy.There were 80 cases,with MicraTM wireless pacemakers successfully implanted,and the pacing success rate was 100%.After treatment,left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),threshold value,impedance,and QT interval were all lower than that before treatment(P<0.05).Left ventricular ejection fraction(LVEF),cardiac output(CO),perception,PR interval,and QRS interval were all higher than that before treatment(P<0.05).Thrombolysis in myocardial infarction(TIMI)grading was better than that before treatment(P<0.05).The proportion of TIMI gradeⅡ or above was 82.50%.Reperfusion injury occurred in 16 of the 80 patients,but there was no death due to reperfusion injury.After 6 months of follow-up,18 patients had adverse cardiovascular events.Conclusion:The combination of wireless pacemaker and PCI can improve cardiac function,myocardial perfusion grading,pacemaker electrical parameters,electrocardiogram parameters in patients with AMI combined with arrhythmia,and with high coronary artery patency rate and high pacing success rate.However,reperfusion injury and adverse cardiovascular events may occur.
